AUTOMATIC CONNECTING-PLUG.

Specification of Letters Patent. Patented Feb. 18, 1913,

application filed January 19, 1912. Serial No. 672.234.

Tool! whom it may concern:

Be it known that I, Jorm N. Mans, a citi- 'zen of the United States; and a resident of 'luos Angeles, Los Angelcs county, and State easily connected or disconnected to or from an ordinary lamp socket.

Another object of my invention is to provide an automaticvconnection plug which plug consists of but a few parts thereby obviating the danger of the some getting out of order.

Another object of my invention is to provide an automatic connection plug which, as above stated consists of but a few parts thereby making the some easy and simple to manufacture.

A further object of my invention is to provide an automatic connection plug which is so constructed as to assure its durability and eilicienc'y.

With the above and other objects in view my invention consists in such details of construction and in the arrangement and combination of I arts as will be hereinafter more full descri ed and specifically pointed out in tlieappcnded claims.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the sev-- eral views'and in which- Figu e 51 is a side elevation of my invention! ig. 2 is a plan view showing the sections which compose my invention open. Fig. 3 is a bottom view of my invention. Fig. 4 is a top plan view of my invention. Fig. 5 is a detail view.

In the accompanying drawings which fully illustrate the preferred form of my invention 1 and 2 designate the two sections of my improved plug which sections are pivoted upon the members 3 as shown at llur-h ot the members is provided with the cut out portions 5 into which cut out portions are adapted to be introduced the velectrical conductors (S as is clearly shown.

Pivotally connected to one of the sections I 1 is an arm 7 as shown at 8. The arm 7 is provided at its lower endwith the binding pin 9 whereby one of the electrical conductors 6 may be connected thereto. The other of the sections 2 is provided with a second arm- 10 which is pivotally secured thereto as shown at 11 and is also provided at its lower end with the binding pin 12. This arm extends above the section 2 and is bent as shown in 13 for a purpose that will be hereafter fully described. I further provide a coil spring 14. which coil spring is adapted to be fastened to the member 2 by any suitable means and. to enter the cut out portion 15 which is formed in the member 1. Particular stress is laid upon the peculiar construction of the cut out portion 15. It will be readily apparent upon reference to the drawings and particularly to Fig. 5"

thereof that the said out out portion is of such construction that it prevents the easy removal of the coil spring. It will be also recognized that the sections 1 and 2 are pressed apart with the medium of the coil spring and that the said sections may be inserted into sockets of dillercnt sizes and held therein by means of the screw threaded members 16.

I desire to lay great stress upon the sim plicity of my invention and it is thought.

that the advantages and novel features of the some will be apparent from the foregoing disclosure.

I desire it to be understood that slight changes in the construction and in the arrungement and combination of the several parts may be resorted to without departing from the spirit of my invention, provided such changes fall within the scope of the appended claims.

tlaving thus fully dcscribcdmy invention what I claim as new and desire to secure by Letters Patent is 1. In on automatic connection plug, two sections having their lower ends pivotally connected together, a coil spring interposed between the upper ends oi said sections whereby they are held out oi engagement with each other and into engagement with the inner periphery of electrical sockets of dili'crcnt (liamcters when inserted therein.

2. In an automatic connection plug members pivoted together at their lower ends one of said members provided with a cut out portion near its up ees end, a. coii spring seated within said cut out portion and adepied to engage the upper encis of eeifi other member whereby they are helei out of emgegemenfi with each other and inio engage.

by the ends of ssh sect-ions may be received into electrical sockets of difi'erent dianieteis.

4. In an automatic connection plug, two sections having their Bower emis nivoteily connected togetheif, one ofseid sections provided with a cut-out portion nexuiis upper end, said cut-out portion having econ sti icted mouth, a coil spring seated within Stud cut-out portion and adapted 0 engage the inner surface of the other efseid members whereby they are held out of engagement with each other and low engagement with theinner pecipheiw of eiee li'icei sockets oi dlfierent dmmeteve wileyxnineeiree therein, said sections preview" wimlomgimsec'ie-ns having their lower ends emi,

from said out out Yortion and means Wbereeoseese dineiiyefstemieg receesesmmi members pic uteri fee the inner sm'fece of seiei-seetions, one end of semi members pro ecting unto sax} receases to which end electrical conductors are 7 connected.

5. in an automatic connection-ph g, two

ivotelly comiecteei together one of said sections provied with s cuooet portion near its upper seid cut-out portion having a consiriciei mouth, a, coii said cut-out portion :mfi adapted to engage the inner surface of the other 0% said members whereby they am held out of engagement with each other and into engagement with the inner periphery of eiectricai sockets of different (ilfiifletQlQ when inserted therein, seici sections provided with longiiliemeily extending recesses, levers plvotenk at e omfi imcrmediaie their 'ends 'to each 0% said sections having 9. bmdm 0st secured to ibeir limes ends to whic mdmg one of said ievcrshaving its outer or upper swing SGMZBd. within post electrical comlueiors are secured and end projecting e short distance above said em sections end. at' right engics so as to form a means of contect'with an electrical eeeizet.
